莲花台水电站主坝为碾压混凝土重力坝,坝址地形与地质条件复杂。混凝土的运输,既要适应峡谷的地形条件,又要适应碾压混凝土的特性。结合工程实际,大坝施工按高程分别采用自卸汽车直接入仓、满管溜槽+仓内自卸汽车倒运、皮带机+布料机组合入仓方式作为坝体混凝土浇筑方案。通过优化混凝土配合比设计,严格控制混凝土施工工序,并加强混凝土的温度和裂缝控制,确保了工程质量。 The main dam of the Lianhuatai Hydropower Station is a roller compacted concrete gravity dam with complex terrain and geological conditions. Concrete transportation, it is necessary to adapt to the canyon topography, but also to adapt to the characteristics of roller compacted concrete. Combined with the actual project, the dam construction by dump truck directly into warehousing, storage tank chute + unloading dump truck, belt + cloth machine combination warehouses as the dam concrete pouring program. By optimizing the concrete mix design, strictly control the concrete construction process, and strengthen the concrete temperature and crack control to ensure the quality of the project.
